DETAILED DESCRIPTION

A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

FIG. 1 is a perspective view of an elevator system 101 including an elevator car 103, a counterweight 105, one or more load bearing members 107, a guide rail 109, a machine 111, a position encoder 113, and an elevator controller 115. The elevator car 103 and counterweight 105 are connected to each other by the load bearing members 107. The load bearing members 107 may be, for example, ropes, steel cables, and/or coated-steel belts. The counterweight 105 is configured to balance a load of the elevator car 103 and is configured to facilitate movement of the elevator car 103 concurrently and in an opposite direction with respect to the counterweight 105 within an elevator shaft 117 and along the guide rail 109.

The load bearing members 107 engage the machine 111, which is part of an overhead structure of the elevator system 101. The machine 111 is configured to control movement between the elevator car 103 and the counterweight 105. The position encoder 113 may be mounted on an upper sheave of a speed-governor system 119 and may be configured to provide position signals related to a position of the elevator car 103 within the elevator shaft 117. In other embodiments, the position encoder 113 may be directly mounted to a moving component of the machine 111, or may be located in other positions and/or configurations as known in the art.

The elevator controller 115 is located, as shown, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103. For example, the elevator controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The elevator controller 115 may also be configured to receive position signals from the position encoder 113. When moving up or down within the elevator shaft 117 along guide rail 109, the elevator car 103 may stop at one or more landings 125 as controlled by the elevator controller 115. Although shown in a controller room 121, those of skill in the art will appreciate that the elevator controller 115 can be located and/or configured in other locations or positions within the elevator system 101. In some embodiments, the elevator controller 115 can be configured to control features within the elevator car 103, including, but not limited to, lighting, display screens, music, spoken audio words, etc.

The machine 111 may include a motor or similar driving mechanism and an optional braking system. In accordance with embodiments of the disclosure, the machine 111 is configured to include an electrically driven motor. The power supply for the motor may be any power source, including a power grid, which, in combination with other components, is supplied to the motor. Although shown and described with a rope-based load bearing system, elevator systems that employ other methods and mechanisms of moving an elevator car within an elevator shaft, such as hydraulics or any other methods, may employ embodiments of the present disclosure. FIG. 1 is merely a non-limiting example presented for illustrative and explanatory purposes.

The elevator car 103 includes at least one elevator door assembly 130 operable to provide access between the each landing 125 and the interior (passenger portion) of the elevator car 103. FIG. 2 depicts the elevator door assembly 130 in greater detail. In the example of FIG. 2, the elevator door assembly 130 includes a door motion guidance track 202 on a header 218, an elevator door 204 including multiple elevator door panels 206 in a center-open configuration, and a sill 208. The elevator door panels 206 are hung on the door motion guidance track 202 by rollers 210 to guide horizontal motion in combination with a gib 212 in the sill 208. Other configurations, such as a side-open door configuration, are contemplated. One or more sensors 214 are incorporated in the elevator door assembly 130. For example, one or more sensors 214 can be mounted on or within the one or more elevator door panels 206 and/or on the header 218. In some embodiments, motion of the elevator door panels 206 is controlled by an elevator door controller 216, which can be in communication with the elevator controller 115 of FIG. 1. In other embodiments, the functionality of the elevator door controller 216 is incorporated in the elevator controller 115 or elsewhere within the elevator system 101 of FIG. 1. Further, calibration processing as described herein can be performed by any combination of the elevator controller 115, elevator door controller 216, a service tool 230 (e.g., a local processing resource), and/or cloud computing resources 232 (e.g., remote processing resources). The sensors 214 and one or more of: the elevator controller 115, the elevator door controller 216, the service tool 230, and/or the cloud computing resources 232 can be collectively referred to as an elevator sensor calibration system 220.

The sensors 214 can be any type of motion, position, force or acoustic sensor, such as an accelerometer, a velocity sensor, a position sensor, a force sensor, a microphone, or other such sensors known in the art. The elevator door controller 216 can collect data from the sensors 214 for control and/or diagnostic/prognostic uses. For example, when embodied as accelerometers, acceleration data (e.g., indicative of vibrations) from the sensors 214 can be analyzed for spectral content indicative of an impact event, component degradation, or a failure condition. Data gathered from different physical locations of the sensors 214 can be used to further isolate a physical location of a degradation condition or fault depending, for example, on the distribution of energy detected by each of the sensors 214. In some embodiments, disturbances associated with the door motion guidance track 202 can be manifested as vibrations on a horizontal axis (e.g., direction of door travel when opening and closing) and/or on a vertical axis (e.g., up and down motion of rollers 210 bouncing on the door motion guidance track 202). Disturbances associated with the sill 208 can be manifested as vibrations on the horizontal axis and/or on a depth axis (e.g., in and out movement between the interior of the elevator car 103 and an adjacent landing 125.

Embodiments are not limited to elevator door systems but can include any elevator sensor system within the elevator system 101 of FIG. 1. For example, sensors 214 can be used in one or more elevator subsystems for monitoring elevator motion, door motion, position referencing, leveling, environmental conditions, and/or other detectable conditions of the elevator system 101.

FIG. 3 depicts the sill 208 in greater detail according to an embodiment. A sill groove 302 can be formed in the sill 208 to assist in guiding horizontal motion of the elevator door 204 of FIG. 2. A shoe 304 can be used to couple the gib 212 to an elevator door panel 206 of FIG. 2. The gib 212 travels within the sill groove 302 to guide and retain the elevator door panel 206. The sill 208 may also include one or more elevated portions 306 and recessed portions 308 that form one or more channels in the sill 208. In the example of FIG. 3, the sill groove 302 is deeper and wider than the recessed portions 308 with respect to the elevated portions 306.

FIG. 4 depicts an elevator sensor calibration device 402 coupled to the door motion guidance track 202 according to an embodiment. Coupling can be achieved using an adhesive, clamp, screws, and/or other type of fastener. The elevator sensor calibration device 402 is shaped to impart an excitation force to an elevator component such as the elevator door 204 of FIG. 2 responsive to horizontal motion of the elevator door 204 upon contact by an elevator component, such as one of the rollers 210. The excitation force can be detected by one or more of the sensors 214 of FIG. 2 as disturbance data to support calibration of the sensors 214.

The elevator sensor calibration device 402 can be sized to wrap at least partially around the door motion guidance track 202. Sizing of the elevator sensor calibration device 402 may be determined based on the desired response characteristics at the point of initial impact of the rollers 210, an amount of desired deflection from the door motion guidance track 202, a length of the disturbance, and a rate of return to the door motion guidance track 202, among other factors. Accordingly, various profiles of the elevator sensor calibration device 402 can be created to induce different responses in the elevator door 204. For instance, as depicted in FIG. 5, the elevator sensor calibration device 402 can include an attachment interface 502 shaped to couple with the door motion guidance track 202. The end view of example profile of FIG. 5 includes a substantially curved transition 505 between an outer surface 504 and a base portion 506 of the elevator sensor calibration device 402, where rollers 210 impact the outer surface 504 and travel in/out of the page in FIG. 5.

FIG. 6 depicts an elevator sensor calibration device 602 coupled to sill 208 according to an embodiment. Coupling can be achieved using an adhesive, clamp, screws, clips and/or other type of fastener or mechanical connection. The elevator sensor calibration device 602 is shaped to impart an excitation force to the elevator door 204 of FIG. 2 responsive to motion of the elevator door 204 upon contact by an elevator component, such as the gib 212 of FIGS. 2 and 3. The excitation force can be detected by one or more of the sensors 214 of FIG. 2 as disturbance data to support calibration of the sensors 214.

The elevator sensor calibration device 602 can be sized to contact an elevated portion 306 (FIG. 3) of the sill 208 when coupled to the sill 208 and positioned to impact the gib 212 and/or shoe 304 (FIG. 3). In some embodiments, the elevator sensor calibration device 602 is sized to fit at least partially within the sill groove 302 (FIG. 3) when coupled to the sill 208 and positioned to impact the gib 212 and/or shoe 304. Sizing of the elevator sensor calibration device 602 may be determined based on the desired response characteristics at the point of initial impact of the gib 212, an amount of desired deflection within the sill groove 302, a length of the disturbance, and a rate of return to normal travel within the sill groove 302, among other factors.

Various profiles of the elevator sensor calibration device 602 can be created to induce different responses in the elevator door 204. For instance, as depicted in FIG. 7, the elevator sensor calibration device 602 can include an attachment interface 702 shaped to couple with the sill 208. The end view of example profile of FIG. 7 includes a plurality of side surfaces 705 between an outer surface 704 and a base portion 706 of the elevator sensor calibration device 602, where the gib 212 (FIG. 3) can impact the outer surface 704 and travel in/out of the page in FIG. 7. The elevator sensor calibration device 602 can be installed in various orientations and positions with respect to the sill groove 302 depending on sizing and placement constraints. In some embodiments, the base portion 706 is substantially planar. In the example of FIGS. 8 and 9, corresponding base portions 806 and 906 have different notch geometries of attachment interfaces 802 and 902 to support contact with different portions of the sill 208 and/or induce different responses in the elevator door 204 (FIG. 2).

FIG. 10 depicts a side view of a lengthwise profile of an elevator sensor calibration device 1002 according to an embodiment. The depicted profile of the elevator sensor calibration device 1002 is an example of a portion of the elevator sensor calibration device 402 (FIG. 4) and/or elevator sensor calibration device 602 (FIG. 6). In the example of FIG. 10, the elevator sensor calibration device 1002 includes a base portion 1006 and a rise ramp 1010 having a first slope 1012 at a first angle (Θ₁) relative to the base portion 1006. The elevator sensor calibration device 1002 also includes a return ramp 1014 having a second slope 1016 at a second angle (Θ₂) relative to the base portion 1006. A mid-portion 1018 is formed between the rise ramp 1010 and the return ramp 1014. An elevator door component impact surface 1020 is formed between a leading impact edge 1022 of the rise ramp 1010, an outer surface 1024 of the rise ramp 1010, an outer surface 1026 of the mid-portion 1018, an outer surface 1028 of the return ramp 1014, and a trailing edge 1030 of the return ramp 1014.

In some embodiments, the first angle (Θ₁) of the rise ramp 1010 is different from the second angle (Θ₂) of the return ramp 1014 to induce different responses. In other embodiments, the first angle (Θ₁) of the rise ramp 1010 is substantially the same as the second angle (Θ₂) of the return ramp 1014 to prevent installation/user errors. In the example of FIG. 10, the outer surface 1026 of the mid-portion 1018 is substantially parallel to the base portion 1006 and offset by a height H. The rise ramp 1010 is an example of a first portion of the elevator sensor calibration device 1002 that can be sized to induce a first vibration profile in one or more elevator door panels 206 (FIG. 2) upon impact with an elevator component 1032 of the elevator door assembly 130 (FIG. 1). The return ramp 1014 is an example of a second portion of the elevator sensor calibration device 1002 that can be sized to induce a second vibration profile in the one or more elevator door panels 206 upon contact with the elevator component 1032 along length L. The elevator component 1032 can be a horizontally translating component, for example, a roller 210 (FIG. 2), a gib 212 (FIG. 2), a shoe 304 (FIG. 3), or other component depending upon the installation location. Although described with respect to elements of elevator door assembly 130, embodiments of the elevator sensor calibration device 402, 602, 1002, can be install on or proximate to many known elevator components of the elevator system 101 of FIG. 1, such as guide rails, pulleys, sheaves, and the like.

FIG. 11 depicts an elevator door assembly 1130 according to an embodiment. In the example of FIG. 11, the elevator door assembly 1130 includes a door motion guidance track 1102, an elevator door 1104 including multiple elevator door panels 1106 in a side-open configuration, and a sill 1108. FIG. 11 further illustrates that multiple elevator sensor calibration devices 402, 602 may be installed at the same time on the door motion guidance track 1102 and sill 1108 respectively depending on the desired response profile.

Referring now to FIG. 12, an exemplary computing system 1200 that can be incorporated into elevator systems of the present disclosure is shown. One or more instances of the computing system 1200 may be configured as part of and/or in communication with an elevator controller, e.g., controller 115 shown in FIG. 1, and/or as part of the elevator door controller 216, service tool 230, and/or cloud computing resources 232 of FIG. 2 as described herein to perform operations of the elevator sensor calibration system 220 of FIG. 2. When implemented as service tool 230, the computing system 1200 can be a mobile device, tablet, laptop computer, or the like. When implemented as cloud computing resources 232, the computing system 1200 can be located at or distributed between one or more network-accessible servers. The computing system 1200 includes a memory 1202 which can store executable instructions and/or data associated with control and/or diagnostic/prognostic systems of the elevator door 204, 1104 of FIGS. 2 and 11. The executable instructions can be stored or organized in any manner and at any level of abstraction, such as in connection with one or more applications, processes, routines, procedures, methods, etc. As an example, at least a portion of the instructions are shown in FIG. 12 as being associated with a control program 1204.

Further, as noted, the memory 1202 may store data 1206. The data 1206 may include, but is not limited to, elevator car data, elevator modes of operation, commands, or any other type(s) of data as will be appreciated by those of skill in the art. The instructions stored in the memory 1202 may be executed by one or more processors, such as a processor 1208. The processor 1208 may be operative on the data 1206.

The processor 1208, as shown, is coupled to one or more input/output (I/O) devices 1210. In some embodiments, the I/O device(s) 1210 may include one or more of a keyboard or keypad, a touchscreen or touch panel, a display screen, a microphone, a speaker, a mouse, a button, a remote control, a joystick, a printer, a telephone or mobile device (e.g., a smartphone), a sensor, etc. The I/O device(s) 1210, in some embodiments, include communication components, such as broadband or wireless communication elements.

The components of the computing system 1200 may be operably and/or communicably connected by one or more buses. The computing system 1200 may further include other features or components as known in the art. For example, the computing system 1200 may include one or more transceivers and/or devices configured to transmit and/or receive information or data from sources external to the computing system 1200 (e.g., part of the I/O devices 1210). For example, in some embodiments, the computing system 1200 may be configured to receive information over a network (wired or wireless) or through a cable or wireless connection with one or more devices remote from the computing system 1200 (e.g. direct connection to an elevator machine, etc.). The information received over the communication network can stored in the memory 1202 (e.g., as data 1206) and/or may be processed and/or employed by one or more programs or applications (e.g., program 1204) and/or the processor 1208.

The computing system 1200 is one example of a computing system, controller, and/or control system that is used to execute and/or perform embodiments and/or processes described herein. For example, the computing system 1200, when configured as part of an elevator control system, is used to receive commands and/or instructions and is configured to control operation of an elevator car through control of an elevator machine. For example, the computing system 1200 can be integrated into or separate from (but in communication therewith) an elevator controller and/or elevator machine and operate as a portion of a calibration system for sensors 214 of FIG. 2.

The computing system 1200 is configured to operate and/or control calibration of the sensors 214 of FIG. 2 using, for example, a flow process 1300 of FIG. 13. The flow process 1300 can be performed by a computing system 1200 of the elevator sensor calibration system 220 of FIG. 2 as shown and described herein and/or by variations thereon. Various aspects of the flow process 1300 can be carried out using one or more sensors, one or more processors, and/or one or more machines and/or controllers. For example, some aspects of the flow process involve sensors, as described above, in communication with a processor or other control device and transmit detection information thereto.

At block 1302, a computing system 1200 collects a plurality of baseline sensor data from one or more sensors 214 during movement of an elevator component 1032. For example, movement can include cycling an elevator door 204, 1104 between an open and a closed position and/or between a closed and open position one or more times.

At block 1304, the computing system 1200 collects a plurality of disturbance data from the one or more sensors 214 while the elevator component 1032 is displaced responsive to contact with an elevator sensor calibration device 402, 602, 1002 during movement of the elevator component 1032.

At block 1306, the computing system 1200 can perform analytics model calibration to calibrate a trained model based on one or more response changes between the baseline sensor data and the disturbance data. For example, time based and/or frequency based analysis can be used to determine how response changes between the baseline sensor data and the disturbance data differs from an expected performance profile. Various adjustments, such as gains, delays, and the like, can be made to account for in the field variations versus ideal performance characteristics. In some embodiments analytics model calibration applies one or more transfer learning algorithms, such as baseline relative feature extraction, baseline affine mean shifting, similarity-based feature transfer, covariate shifting by kernel mean matching, and/or other transfer learning techniques known in the art, to develop a transfer function for calibrating features of a trained model based on response changes between the baseline sensor data and the disturbance data. The trained model can establish a baseline designation, a fault designation, and one or more fault detection boundaries for the elevator component 1032. The result of applying a learned transfer function to the trained model can include calibration of a fault data signature and one or more detection boundary (e.g., defining fault/no fault classification criteria) according to the specific waveform propagation characteristics observed in the disturbance data. A calibrated fault detection boundary and a calibrated fault designation (i.e., data signature) can represent a calibrated analytics model. A fault designation can include, for instance, one or more of: a roller fault, a track fault, a sill fault, a door lock fault, a belt tension fault, a car door fault, a hall door fault, and other such faults associated with elevator system 101.

In some embodiments, multiple movement speed profiles can be applied to modify a rate of movement (e.g., opening/closing the elevator door 204, 1104) while collecting the baseline sensor data and the disturbance data. Changing the speed and/or acceleration of elevator component 1032 in various calibration tests can further enhance the ability reach particular frequency ranges when impacting the elevator sensor calibration device 402, 602, 1002. Further features may be observed by adjusting the placement position of the elevator sensor calibration device 402, 602, 1002 and/or contacting more than one instance of the elevator sensor calibration device 402, 602, 1002 during movement of the elevator component 1032.

As described herein, in some embodiments various functions or acts may take place at a given location and/or in connection with the operation of one or more apparatuses, systems, or devices. For example, in some embodiments, a portion of a given function or act may be performed at a first device or location, and the remainder of the function or act may be performed at one or more additional devices or locations.

Various mechanical components known to those of skill in the art may be used in some embodiments.

Embodiments may be implemented as one or more apparatuses, systems, and/or methods. In some embodiments, instructions may be stored on one or more computer program products or computer-readable media, such as a transitory and/or non-transitory computer-readable medium.
